I want to use Scratch 2 on raspbian. I googled and found that latest raspbian buster comes with Scratch 3 (which I don't want to use). Based on further searches, I have now downloaded raspbian Stretch (2019-04-08-raspbian-stretch).
If I install above raspbian image afresh, how can I have the latest OS updates (e.g. security fixes) but keep using Scratch 2. I mean will it automatically upgrade to buster?
PS: I want to use the offline and not the online version of scratch.
